Democrats go out of their way to propose and support specific proposals for all types of groups, especially Hispanics. You don't really see them throwing on sombreros and talking about Selena when they're reaching out to them. Yet with black people it's time to dance and start saying "ain't" like slayren. I'm voting for Biden. I have zero qualms with him, in part because my main interest is winning. But let's be real: black people literally saved his campaign from collapse, and while I'm sure he'll dole out money to HBCUs if he becomes president...we aren't going to see any real tangible effort to support black interests or businesses. Everyone else gets courted, yet with black people it's just an expectation you vote the right way.
That's not to say democrats never do anything for black people. But a lot of the heavy lifting is done on the state and local level, especially in the south. Killer Mike tried to explain this to Bernie stans to no avail, but local democrats and orgs do a lot of civil rights work down there and deserve recognition. But on the national level? It's moreso...preventing worse shit from happening. IE defending the CRA, defending the VRA, nominating some decent judges here or there, etc. And lets not forget the ACA greatly helped a loooot of black people. I don't want to say nothing good is done but man. More could and SHOULD be done, given the level to which black people vote for these dudes. VS bending over backwards to appease a demographic that's a few years away from assimilation into whiteness, and already well versed in anti-black racism.
